Unimplemented: Read as ‘0’
TRISIO<5:0>: GPIO Tri-State Control bit
1 = GPIO pin configured as an input (tri-stated)
0 = GPIO pin configured as an output
Unimplemented: Read as ‘0’
WPU<5:4>: Weak Pull-up register bit
1 = Pull-up enabled
0 = Pull-up disabled
Unimplemented: Read as ‘0’
WPU<2:0>: Weak Pull-up register bit
1 = Pull-up enabled
0 = Pull-up disabled
